Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A communication control apparatus comprising: a processor configured to: fix a number of sets of data to be inserted into one packet by a communication apparatus according to a wireless quality with the communication apparatus, the set is a data group requested by a failure detection algorithm, which is obtained by gathering operation management data of different classifications in sampling units; determine, in consideration of a slope of a regression line, whether the wireless quality with the communication apparatus satisfies a requested quality based on the data for a plurality of times of sampling operation management data transmitted from the communication apparatus immediately before a timing of the determination; decrease the number of sets when the wireless quality does not satisfy the requested quality; and notify the communication apparatus of the number of sets fixed at the fixing.
This invention relates to wireless communication systems where operation management data is transmitted between devices. The problem addressed is ensuring reliable data transmission despite varying wireless quality, particularly when using failure detection algorithms that require grouped data sets. The solution involves dynamically adjusting the number of data sets inserted into each packet based on real-time wireless quality assessments. The apparatus includes a processor that fixes the number of data sets per packet according to the current wireless quality with a communication device. Each data set is a group of operation management data from different classifications, gathered in sampling units, and required by a failure detection algorithm. The processor evaluates wireless quality by analyzing the slope of a regression line derived from multiple sampling instances of operation management data received just before the determination. If the wireless quality falls below a required threshold, the number of data sets per packet is reduced to improve transmission reliability. The processor then notifies the communication device of the adjusted number of sets. This approach optimizes data transmission efficiency and reliability by dynamically adapting to wireless conditions, ensuring that failure detection algorithms receive sufficient data while minimizing packet loss. The system avoids overloading the wireless channel when quality is poor, thereby maintaining stable communication.
2. The communication control apparatus according to claim 1 , wherein the processor is further configured to estimate the number of sets with which the wireless quality satisfies the requested quality based on a quality of the packet transmitted from the communication apparatus and fix the estimated number of sets as the number of sets.
This invention relates to wireless communication systems, specifically to a communication control apparatus that optimizes the number of communication sets (e.g., wireless links or connections) based on signal quality. The problem addressed is ensuring efficient resource allocation while meeting quality-of-service (QoS) requirements in dynamic wireless environments. The apparatus includes a processor that monitors the quality of packets transmitted from a communication device. By analyzing this data, the processor estimates how many sets (e.g., wireless channels or connections) can maintain the requested quality level. The estimated number is then fixed as the operational number of sets, ensuring that the system neither over-allocates resources nor fails to meet performance demands. This dynamic adjustment helps balance throughput, latency, and reliability in real-time. The processor may also determine the requested quality based on factors like application requirements or network conditions. The system can adapt to changes in wireless quality, such as interference or signal degradation, by recalculating the optimal number of sets. This approach improves efficiency in wireless networks, particularly in scenarios with fluctuating demand or environmental interference. The invention is applicable to various wireless technologies, including cellular, Wi-Fi, or IoT networks, where maintaining consistent performance is critical.
3. The communication control apparatus according to claim 1 , wherein an index representing the wireless quality is a link quality indicator (LQI).
A communication control apparatus is designed to manage wireless communication links, particularly in environments where signal quality can vary. The apparatus monitors the wireless quality of communication links between devices, such as in mesh networks or other multi-node systems, to ensure reliable data transmission. A key feature is the use of an index to quantify wireless quality, specifically a link quality indicator (LQI). The LQI is a metric derived from received signal characteristics, such as signal strength and noise levels, providing a numerical representation of link reliability. The apparatus may use this LQI to make decisions, such as selecting optimal communication paths, adjusting transmission parameters, or triggering retransmissions when quality falls below a threshold. By incorporating LQI-based assessments, the system improves overall network performance, reduces packet loss, and enhances energy efficiency in wireless networks. The apparatus may also include mechanisms to dynamically update LQI values as environmental conditions change, ensuring continuous adaptation to varying wireless conditions. This approach is particularly useful in applications like IoT, industrial automation, and smart infrastructure, where stable and efficient wireless communication is critical.
4. A communication control system comprising a communication apparatus and a communication control apparatus that receives data from the communication apparatus, wherein the communication control apparatus includes: a first processor configured to: fix a number of sets of data to be inserted into one packet by the communication apparatus according to a wireless quality with the communication apparatus, the set is a data group requested by a failure detection algorithm, which is obtained by gathering operation management data of different classifications in sampling units; determine, in consideration of a slope of a regression line, whether the wireless quality with the communication apparatus satisfies a requested quality based on the data for a plurality of times of sampling operation management data transmitted from the communication apparatus immediately before a timing of the determination; decrease the number of sets when the wireless quality does not satisfy the requested quality; and notify the communication apparatus of the number of sets fixed at the fixing, and the communication apparatus includes: a second processor configured to: measure a communication status; and insert the data for the number of sets notified at the notifying into one packet and transmit the packet to the communication control apparatus when transmitting the data indicating a result of the measurement.
This invention relates to a communication control system for optimizing data transmission in wireless networks, particularly where communication quality fluctuates. The system addresses the challenge of maintaining reliable data transmission while adapting to varying wireless conditions, ensuring efficient operation management data collection without excessive packet overhead. The system includes a communication apparatus and a communication control apparatus. The communication control apparatus receives operation management data from the communication apparatus, which is grouped into sets based on different classifications and sampling units. A first processor in the control apparatus dynamically adjusts the number of data sets inserted into each packet based on wireless quality. It evaluates wireless quality by analyzing the slope of a regression line derived from multiple sampling instances of operation management data transmitted just before a determination is made. If the wireless quality falls below a required threshold, the number of data sets per packet is reduced to improve transmission reliability. The adjusted number of sets is then communicated to the communication apparatus. The communication apparatus, equipped with a second processor, measures communication status and transmits data in packets containing the specified number of sets. This adaptive approach ensures efficient data transmission while minimizing packet loss in unstable wireless environments. The system is particularly useful in industrial or IoT applications where consistent data collection is critical.
5. A non-transitory computer-readable recording medium storing therein a communication control program that causes a computer to execute a process comprising: fixing a number of sets of data to be inserted into one packet by a communication apparatus according to a wireless quality with the communication apparatus, the set is a data group requested by a failure detection algorithm, which is obtained by gathering operation management data of different classifications in sampling units; determining, in consideration of a slope of a regression line, whether the wireless quality with the communication apparatus satisfies a requested quality based on the data for a plurality of times of sampling operation management data transmitted from the communication apparatus immediately before a timing of the determination; decreasing the number of sets when the wireless quality does not satisfy the requested quality; and notifying the communication apparatus of the fixed number of sets.
This invention relates to wireless communication systems where operation management data is transmitted between devices, addressing the challenge of maintaining data integrity and communication efficiency under varying wireless conditions. The system dynamically adjusts the amount of data transmitted in each packet based on real-time wireless quality assessments to ensure reliable failure detection while optimizing bandwidth usage. The process involves a computer program that first fixes the number of data sets to be inserted into a single packet, where each set is a group of operation management data from different classifications, gathered in sampling units. These data sets are required by a failure detection algorithm to monitor system performance. The system then evaluates the wireless quality with the communication apparatus by analyzing the slope of a regression line derived from multiple sampling instances of operation management data transmitted immediately before the evaluation. If the wireless quality does not meet the required standards, the number of data sets per packet is reduced to mitigate transmission errors. The adjusted number of sets is then communicated to the communication apparatus for implementation. This approach ensures that the failure detection algorithm receives sufficient data for accurate monitoring while adapting to fluctuating wireless conditions, thereby balancing data integrity and communication efficiency.
